“…Among the Fontinalicaridinae from the Neotropical region, some species of Siolicaris exhibit a short apophysis, and the distal spine of the apophysis is fused or lost in all species of the genus, except for S. sandhya (Ranga Reddy 2011). A long apophysis can be observed in Iticocaris and in Brasilibathynellocaris (Corgosinho et al , 2012a, but no trace of a distal spine can be observed in the adult, with the exception of a heteromorphic male of B. salvadorensis (Noodt, 1962) and the copepodid V of the same species , with a 2-segmented P3 exp with a distal spine not fused to exp-2.

Eirinicaris antonioi gen. et sp. n. (Parastenocaridinae) is described from the Brazilian rocky savannas, an ecosystem under heavy anthropogenic pressure. The subfamily is distributed worldwide, with representatives in Africa, Asia, Australia, Europe, and North America. This is the first time a non-Remaneicaris Parastenocaridinae is described from a Neotropical region indicating that Parastenocaridinae species were already present in a vast geographical area, before the split of the Gondwana. The new taxon is included within the subfamily Parastenocaridinae based on the following characters: 1) segments 5, 6, and 7 of the male antennules forming a functional unit for clasping the female; 2) segment 7 with small process at the inner margin, forming an incipient "pocket-knife" structure with segment 6; 3) last segment pointing medially when closed; 4) the endopod of female leg 3 one-segmented and spiniform, without distal seta; 5) the apophysis and terminal seta of the exopod of male leg 3 are fused; 6) the genital field is rectangular and much broader than the height in the female; 7) the group of three lateral setae I, II, and III of the furca and the dorsal seta are situated at the same level in the female; and 8) the basis of leg 1 has an inner seta. The new taxon can be distinguished from all other Parastenocaridinae genera by the unique sexually dimorphic telson and furca. In the male, the dorsal seta is inserted at the midlength of the furca and setae I, II, and III are displaced anteroventrally. A phylogenetic analysis of the subfamily Parastenocaridinae is given based on the description of the type species of each genus and available descriptions of all Parastenocaridinae species. Eirinicaris gen. n. is the sister taxon of a clade formed by Kinnecaris and Monodicaris, sharing with them the long male and female leg 5 with a long spiniform process, and with Kinnecaris, a distal pore on the spiniform process.

“…13d). Corgosinho et al (2012) described this character as a synplesiomorphy of the subfamily Fontinalicaridinae Schminke, 2010, making the genus Proserpinicaris polyphyletic, and rejected the validity of this genus. In fact, in the original description of the subfamily Fontinalicaridinae, Schminke (2010) clearly stated that "on the basis of male leg 4 Parastenocaridinae have (if present) spinules either medially of the endopod or at its base; Fontinalicaridinae have them between endopod and exopod".…”

“…It must be taken into account that in Proserpinicaris the basis of male P4 carries two 'appendices' or 'elements' ("Anhänge" according to Lang 1948), it is not always easy to tell apart the endopod from the hyaline process (Corgosinho et al 2012). However, P. proserpina, type species for the genus, and the species of Proserpinicaris discussed in this paper, share a clearly recognisable endopod, inserted outwardly to the hyaline structure, as well as all the diagnostic feature of the genus (see the section "Taxonomic definition and affinities of three new species"), and are clearly representatives of the genus.…”

“…young Karanovic, Cho &Lee, 2012. The controversial nature of the key synapomorphy of the genus Proserpinicaris, i.e., the presence of a hyaline process on the anterior surface of basis, between the exopod and endopod, was discussed by Corgosinho et al (2012), but the genus definition of Karanovic et al (2012) was accepted by other authors while describing new species of Proserpinicaris (Totakura et al 2014; but see Walter & Boxshall 2019). We will follow Karanovic et al (2012) only in part, as we will discuss in detail.…”

“…However, the same authors advocated the need of adding additional parastenocaridid species to the analysis, in order to improve the understanding of the family. In the context of our ongoing research on the microcrustacean fauna of caves in Southern Italy (Cottarelli et al 2012;Bruno et al 2017), we carried out new campaigns in caves of Calabria (Southern peninsular Italy) and collected new material which we describe and analyse in the present paper, where we aim to: 1) describe and taxonomically define three new species of Parastenocarididae; 2) verify the validity of the genus Cottarellicaris and the possible affinities between Cottarellicaris and the morphologically sister genus Stammericaris, based on both morphological and molecular evidences; 3) provide insights on the genus Proserpinicaris as defined by Karanovic et al (2012) and discussed by Corgosinho et al (2012) also based on the development of the P4 endopod in the last copepodid stage of some species of this genus; 4) widen the biogeographic and ecological knowledge of the three genera.…”

We describe three new parastenocaridid: Cottarellicaris sanctiangeli Bruno & Cottarelli sp. nov., Stammericaris vincentimariae Bruno & Cottarelli sp. nov. and Proserpinicars specincola Bruno & Cottarelli sp. nov., collected in the pools of five different caves located in Calabria (Southern Italy). We conducted a phylogenetic analysis based on the mitochondrial COI and ribosomal 18S sequences of C. sanctiangeli sp. nov. and S. vincentimariae sp. nov., and of four more species of Stammericaris and one Proserpinicaris available from literature. Based on the molecular study, the specimens of C. sanctiangeli sp. nov. are clearly separated from the species belonging to the closely-related genus Stammericaris. The morphological and molecular data indicate that the genera belonging to the two subfamilies Parastenocaridinae and Fontinalicaridinae form two monophyletic and distinct clades, thus supporting their status. We also provide insights on the genus Proserpinicaris based on morphological data only; in particular, the most important synapomorphic character of the genus, i.e., the taxonomic value of the hyaline structure inserted on the anterior surface of the male leg 4 basis, is discussed based on the development of the P4 endopod, as observed in the last copepodid stage of some species of this genus. Finally, we widen the biogeographic and ecological knowledge of the three genera.
